Installation
STEP 1 Determine the header bracket location
To preventpossible SERIOUS INJURY or DEATH:
l Header bracketMUSTbe RIGIDLY fastened to structural supporton header wall or ceiling,
otherwise garage door mightNOT reverse when required.DO NOT install header bracketover
drywall.
l Concrete anchors MUST be used if mounting header bracketor 2x4 into masonry.

hardware,ALL of which are under EXTREME tension.
l ALWAYS call a trained door systemstechnician if garage door binds, sticks, or is out of balance.
An unbalanced garage door mightNOT reverse when required.
Installation procedures varyaccording to garage door types.Followthe instructions which applyto your
door.
1. Close the door and mark the inside vertical centerline of the garage door.
2. Extend the line onto the header wall above the door.You can fasten the header bracket within
4 feet(1.22 m) of the leftor right ofthe door center onlyifa torsion spring or center bearing
plate is in the way; or you can attach it to the ceiling (see page 13) when clearance is minimal.
(It may be mounted on the wall upside down if necessary, to gain approximately 1/2" (1 cm). If
you need to install the header bracketon a 2x4 (on wall or ceiling), use lag screws (not
provided) to securelyfasten the 2x4 to structural supportsasshown here and on page 13.
3. Open your door to the highestpoint oftravel asshown.Draw an intersecting horizontal line on
the header wall 2" (5 cm) above the high point:
l 2" (5 cm) above the high pointfor sectional door and one-piece door with track.
l 8" (20 cm) above the high point for one-piece door without track.
Thisheight will provide travel clearance for the top edge of the door.NOTE: If the total number of inches
exceeds the height available in your garage, use the maximum height possible, or refer to page 13 for
